KernTune: Self-tuning Linux kernel performance using support vector machines
(Association for Computing Machinery, 2007)
Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
A Softbridge with carrier grade reliability using JAIN SLEE
(Telkom, 2004)
We have built a SoftBridge prototype within a JAIN (Java APIs for the Integrated Network) SLEE (Service Logic Execution Environment). A SoftBridge is a semi-synchronous multimodal IP (Internet Protocol) -based communication ...
A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
(Telkom, 2000)
The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ...
Handheld fast-track feedback instant messaging
(Telkom, 2003)
As mobile devices and networks become more data-centric, text messaging requires an extension of co-presence capabilities for better interactive discussion between input/output handicapped handheld users and their free ...
User interfaces for communication bridges across the digital divide
(Springer-Verlag, 2006)
Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centred approach to learn how interaction techniques can compensate for poor communication across ...
An Interoperable signaling solution for IP-based Next Generation Networks
(Telkom, 2000)
Current VoIP signaling protocols are interoperable with the PSTN SS7 via H.323-to-SS7 or SIP-to-SS7 gateways. As we move toward the Next Generation Network, the PSTN falls away and we work toward carrier-grade VoIP ...
Affective gesture feedback Instant Messaging on handhelds
(Institute of Electrical and Electronics Engineers, Inc., 2004)
Mobile devices and mobile networks are becoming more data-centric (evident in Japanese I-mode) even as mobile network voice Average Revenue Per User are declining, new stream of data services are required which must take ...
Instant Messaging on handhelds: affective feedback
(Telkom, 2004)
A text only Instant Messaging (IM) built on the IETF open standard SIP/SIMPLE has been developed in line with our proposed introduction of a user-defined text Hotkey feature. These act as an on-click Affective Gesture (AG): ...
